Abstract: Systems and methods for specifying UE power control allocation for simultaneous transmission of PRACH in a secondary serving cell and PUCCH/PUSCH/SRS in a different serving cell in another timing advance group are disclosed. Rules are provided for prioritizing transmission of PRACH and/or other UL channels/signals. Additionally, UE power allocation is controlled for misaligned subframes across different timing advance groups. Latency of UL synchronization for a secondary serving cell is reduced by prioritizing PRACH retransmission.

Abstract: A method of operating a time division duplex (TDD) wireless communication system is disclosed. The method includes establishing communications with a remote transceiver. A subframe configuration including static and flexible subframes is determined and transmitted to the remote transceiver. A channel state information (CSI) report is received from the remote transceiver in response to the subframe configuration.

Abstract: A method of operating a long term evolution (LTE) communication system on a shared frequency spectrum is disclosed. A user equipment (UE) is initialized on an LTE frequency band. A base station (eNB) monitors the shared frequency spectrum to determine if it is BUSY. The eNB transmits to the UE on the shared frequency spectrum if it is not BUSY. The eNB waits for a first time if it is BUSY and directs the UE to vacate the shared frequency spectrum after the first time.

Abstract translation: 公开了一种在共享频谱上操作长期演进（LTE）通信系统的方法。 在LTE频带上初始化用户设备（UE）。 基站（eNB）监视共享频谱以确定其是否为BUSY。 如果eNB不是BUSY，则eNB在共享频谱上向UE发送。 如果它是BUSY，则eNB等待第一次，并且指示UE在第一次之后腾出共享频谱。

Abstract: A method and user equipment for channel state information (CSI) reporting are described. The method receives a channel quality indicator request. The method determines a channel quality indicator based on a CSI reference resource. The method transmits a CSI report that includes the channel quality indicator via a Physical Uplink Control CHannel (PUCCH) on an uplink subframe. The CSI reference resource belongs to a subframe subset for which the CSI report is sent. The CSI reference resource includes overhead of Demodulation Reference Signals according to a corresponding rank report.

Abstract: Embodiments of the invention are directed to a cellular communication network that can determine whether communications between one base station-UE pair may interfere with another UE that is in the same cell or a different cell. The network identifies interference parameters associated with interference signals that may be received by a UE. The interference signals may be generated by the base station itself, such as communications with other UEs, or by a neighboring base station. The base station transmits the interference parameters to the UE. The UE receives the one or more parameters comprising information about signals expected to cause intra-cell or inter-cell interference. The UE then processes received signals using the one or more parameters to suppress the intra-cell or inter-cell interference.

Abstract: Carrier aggregation allows concurrent transmission on multiple component carriers (CC) to increase the data rate. A user equipment (UE) device in a cellular network provides periodic or aperiodic channel state information of the DL channel to a base station (eNB) for each of the aggregated CCs. The UE receives two or more reference signals corresponding to two or more aggregated CCs from an eNB. The UE computes a plurality of channel state information (CSI) reports for each of two or more aggregated CCs derived from the two or more reference signals. The UE receives a positive CSI request from the eNB for a CSI report and transmits CSI feedback to the eNB comprising one or more CSI reports selected from the plurality of CSI reports.

Abstract: Systems and methods for specifying UE power control allocation for simultaneous transmission of PRACH in a secondary serving cell and PUCCH/PUSCH/SRS in a different serving cell in another timing advance group are disclosed. Rules are provided for prioritizing transmission of PRACH and/or other UL channels/signals. Additionally, UE power allocation is controlled for misaligned subframes across different timing advance groups. Latency of UL synchronization for a secondary serving cell is reduced by prioritizing PRACH retransmission.
